Through Hole Resistors

Through hole resistors are passive electrical components used in electronic circuits to regulate the current flow, manage transient voltages, and change the voltage levels in the circuit. Through hole resistors are presently being used to replace the aging and bulky wire wound resistors that are difficult to install, expensive, and lack power. H4457RBYA is a type of Through hole resistor.

H4457RBYA Application Field and Working Principle

H4457RBYA is a high-power, through-hole metal oxide resistor manufactured by TE Connectivity. It is designed for use in applications that require heat resistance in a power supply, and is reliable in operation. It is suitable for power supply applications including power supplies, DC/DC converters, and other power management circuits.

This type of through hole resistor functions by using a resistive material (usually metal oxide) to reduce the amount of current that is flowing through a circuit. The material is designed to resist current, not completely halt it, so the amount of current that is passed through can be regulated. This voltage regulation is achieved through Ohm\'s Law, which states that the voltage across a resistor is equal to the current multiplied by the resistance.

The presence of the resistor on the circuit path with its known resistance allows the voltage between the two points on the path to be controlled. In cases where voltage regulation is required, additional electrical current can be provided to account for the difference between the input and output voltage. This allows for more efficient operation, without wasting energy as heat.

H4457RBYA through-hole resistors provide superior performance in applications where heat-resistance capabilities are necessary. These resistors have a wide operating temperature range of -55 to +175°C with power ratings of up to 2W. They feature a stable, low- inductance design to handle higher peak currents and surges, and can be used in both AC and DC circuits.

H4457RBYA Through hole resistors offer superior performance in applications where heat resistance and low-inductance are required. The stability of these resistors makes them ideal for use in power supplies, DC/DC converters, and other power management circuits. The wide operating temperature range and high power rating make them suitable for use in a variety of applications.
